Chapter 2: System Safety
Chapter 2
System Safety
2-1 Overview
This chapter provides a quick setup checklist to get your chassis up and running.
Following the steps in order given should enable you to have your chassis set up
and operational within a minimal amount of time. This quick setup assumes that you
are an experienced technician, famailiar with common concepts and terminology.
2-2 Warnings and Precautions
You should inspect the box the chassis was shipped in and note if it was damaged
in any way. If the chassis itself shows damage, le a damage claim with carrier
who delivered your system.
Decide on a suitable location for the rack unit that will hold that chassis. It should
be situated in a clean, dust-free area that is well venilated. Avoid areas where heat,
electrical noise and eletromagnetic elds are generated.
You will also need the system placed near at least one grounded power outlet. When
congured, the SC847 chassis includes one power supply. "R" models include a
redundant power supply and require two grounded outlets.
2-3 Preparing for Setup
The SC847 chassis includes a set of rail assemblies which includes mounting brack-
ets and mounting screws you will need to install the systems into the rack. Please
read this manual in its entirety before you begin the installation procedure.
SC847 Chassis Manual
2-2
2-4 Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself from harm
and the SC847 from damage:
Be aware of the locations of the power on/off switch on the chassis as well •
as the room’s emergency power-off switch, disconnection switch or electrical
outlet. If an electrical accident occurs, you can then quickly remove power from
the system.
Do not work alone when working with high voltage components.•
Power should always be disconnected from the system when removing or install-•
ing main system components, such as the serverboard, memory modules (not
necessary for hot swappable drives). When disconnecting power, you should rst
power down the system with the operating system and then unplug the power
cords from all the power supply modules in the system.
When working around exposed electrical circuits, another person who is fa-•
miliar with the power-off controls should be nearby to switch off the power, if
necessary.
Use only one hand when working with powered-on electrical equipment. This •
is to avoid making a complete circuit, which will cause electrical shock. Use
extreme caution when using metal tools, which can easily damage any electrical
components or circuit boards they come into contact with.
Do not use mats designed to decrease electrostatic discharge as protection from •
electrical shock. Instead, use rubber mats that have been specically designed
as electrical insulators.
The power supply power cord must include a grounding plug and must be •
plugged into grounded electrical outlets.
Serverboard battery: CAUTION - There is a danger of explosion if the onboard •
battery is installed upside down, which will reverse its polarities This battery
must be replaced only with the same or an equivalent type recommended by
the manufacturer. Dispose of used batteries according to the manufacturer’s
instructions.
2-3
Chapter 2: System Safety
Please handle used batteries carefully. Do not damage the battery in any way; •
a damaged battery may release hazardous materials into the environment. Do
not discard a used battery in the garbage or a public landll. Please comply
with the regulations set up by your local hazardous waste management agency
to dispose of your used battery properly.
2-5 General Safety Precautions
Keep the area around the chassis clean and free of clutter.•
Place the chassis top cover and any system components that have been re-•
moved away from the system or on a table so that they won’t accidentally be
stepped on.
While working on the system, do not wear loose clothing such as neckties and •
unbuttoned shirt sleeves, which can come into contact with electrical circuits or
be pulled into a cooling fan.
Remove any jewelry or metal objects from your body, which are excellent metal •
conductors that can create short circuits and harm you if they come into contact
with printed circuit boards or areas where power is present.
After accessing the inside of the system, close the system back up and secure •
it to the rack unit with the retention screws after ensuring that all connections
have been made.
2-6 System Safety
Electrostatic discharge (ESD) is generated by two objects with different electrical
charges coming into contact with each other. An electrical discharge is created to
neutralize this difference, which can damage electronic components and printed
circuit boards. The following measures are generally sufcient to neutralize this
difference before contact is made to protect your equipment from ESD:
Do not use mats designed to decrease electrostatic discharge as protection from •
electrical shock. Instead, use rubber mats that have been specically designed
as electrical insulators.
Use a grounded wrist strap designed to prevent static discharge.•
Keep all components and printed circuit boards (PCBs) in their antistatic bags •
until ready for use.
SC847 Chassis Manual
2-4
Touch a grounded metal object before removing any board from its antistatic •
bag.
Do not let components or PCBs come into contact with your clothing, which may •
retain a charge even if you are wearing a wrist strap.
Handle a board by its edges only; do not touch its components, peripheral chips, •
memory modules or contacts.
When handling chips or modules, avoid touching their pins.•
Put the serverboard and peripherals back into their antistatic bags when not •
in use.
For grounding purposes, make sure your computer chassis provides excellent •
conductivity between the power supply, the case, the mounting fasteners and
the serverboard.

Chapter 3: System Interface
Chapter 3
System Interface
3-1 Overview
There are several LEDs on the control panel as well as others on the drive carriers
to keep you constantly informed of the overall status of the system as well as the
activity and health of specic components. Most SC847 models have two buttons
on the chassis control panel: A reset button and a power on/off switch. This chapter
explains the meanings of all LED indicators and the appropriate responses you
may need to take.
Figure 3-1: Control Panel
SC847 Chassis Manual
3-2
3-3 Control Panel LEDs
The control panel located on the left handle of the SC847 chassis has ve LEDs.
These LEDs provide you with critical information related to different parts of the
system. This section explains what each LED indicates when illuminated and any
corrective action you may need to take.
Power: The main power button is used to apply or remove power from the power
supply to the server system. Turning off system power with this button removes
the main power but keeps standby power supplied to the system. Therefore, you
must unplug system before servicing.
3-2 Control Panel Buttons
There are two push-buttons located on the left handle of the chassis. These are
(in order from top to bottom) a power on/off button and a reset button.
Power: Indicates power is being supplied to the system's power supply units. This
LED should normally be illuminated when the system is operating.
HDD: Indicates IDE channel activity. SAS/SATA drive, and/or DVD-ROM drive
activity when ashing.
Reset: The reset button is used to reboot the system.
3-3
Chapter 3: System Interface
NIC1: Indicates network activity on GLAN1 when ashing.
NIC2: Indicates network activity on GLAN2 when ashing.

!
Power Failure: When this LED ashes, it indicates a failure in the redundant power
supply.
Overheat /Fan Fail: -When this LED ashes, it indicates a fan failure. When con
tinuously on (not ashing) it indicates an overheat condition, which may be caused
by cables obstructing the airow in the system or the ambient room temperature
being too warm. Check the routing of the cables and make sure all fans are pres-
ent and operating normally. You should also check to make sure that the chassis
covers are installed. Finally, verify that the heatsinks are installed properly. This
LED will remain ashing or on as long as the overheat condition exists.
SC847 Chassis Manual

3-4 Drive Carrier LEDs
The SC847 chassis uses SAS or SATA drives.
SAS/SATA Drives
Each SAS/SATA drive carrier has two LEDs.
Blue:•
Solid on = Drive is present and available.
Blinking = Drive is actively being accessed.
Each Serial ATA drive carrier has a blue LED. When illuminated in a solid
on state, this blue LED (on the front of the SAS/SATA drive carrier) indicates
drive activity. A connection to the SAS/SATA backplane enables this LED to
blink on and off when that particular drive is being accessed.
Red:•
Solid on = Drive failure
Blinking = RAID activity
When the red LED is blinking, it indicates that the system is either building,
initializing or rebuilding RAID.

Installing the Motherboard
Review the documentation that came with your motherboard. Become familiar 1.
with component placement, requirements, precautions, and cable connec-
tions.
Open the chassis cover and remove the chassis from any power source.2.
As required by your motherboard, install standoffs in any areas that do not 3.
have a permanent standoff. To do this:
A. Place a hexagonal standoff screw through the bottom the chassis.
B. Secure the screw with the hexagon nut (rounded side up).
Figure 4-11: Chassis Standoffs
Permanent and Optional Standoffs
Standoffs prevent short circuits by securing space between the motherboard and
the chassis surface. The SC847 chassis includes permanent standoffs in locations
used by most motherboards. These standoffs accept the rounded Phillips head
screws included in the SC847 accessories packaging.
Some motherboards require additional screws for heatsinks, general components
and/or non-standard security. Optional standoffs are included to these mother-
boards. To use an optional standoff, you must place the hexagonal screw through
the bottom the chassis and secure the screw with the hexagon nut (rounded side
up).

4-6 Installing the Air Shroud
Air shrouds concentrate airow to maximize fan efciency. The SC847 chassis air
shroud does not require screws for its installation. The SC847 air shroud is designed
with removeable break-away tabs that allow the air shroud to be adjusted to t a
variety of motherboards.
Installing the Air Shroud
Disconnect the chassis from any power source and remove the chassis cover.1.
Place the air shroud in the chassis. The air shroud ts behind the fans and 2.
beside to the power supply.
After checking the t of the air shroud, remove any break-away tabs neces-3.
sary to ensure a proper t with the motherboard.

Chapter 4: Chassis Setup and Maintenance
4-7 Checking the Server's Air Flow
Checking the Air Flow
1. Make sure there are no objects to obstruct airow in and out of the server. In
addition, if you are using a front bezel, make sure the bezel's lter is replaced
periodically.
2. Do not operate the server without drives or drive trays in the drive bays. Use
only recommended server parts.
3. Make sure no wires or foreign objects obstruct air ow through the chassis. Pull
all excess cabling out of the airow path or use shorter cables.
The control panel LEDs inform you of system status. See “Chapter 3: System
Interface” for details on the LEDs and the control panel buttons.
In most cases, the chassis power supply and fans are pre-installed. If you need to
install fans continue to the Systems Fan section of this chapter. If the chassis will be
installed into a rack, continue to the next chapter for rack installation instructions

Seven hot-swappable, heavy-duty fans provide cooling for the chassis. These fans
circulate air through the chassis thereby lowering the chassis internal tempera-
ture.
4-8 System Fans
Replacing a System Fan
Open the chassis while the power is running to determine which fan has 1.
failed. (Never run the server for an extended period of time with the chassis
cover open.)
Remove the failed fan's power cord from the serverboard.2.
Press the fan release tab to lift the failed fan from the chassis and pull it 3.
completely out of the chassis.
Place the new fan into the vacant space in the housing while making sure the 4.
arrows on the top of the fan (indicating airow direction) point in the same
direction as the arrows on the other fans.
Check that the fan is working properly before replacing the chassis cover.5.

4-9 Power Supply
The SC847 chassis has a 1400 Watt high-efciency redundant power supply. This
power supply is auto-switching capable. This enables it to automatically sense and
operate at a 100v to 240v input voltage. An amber light will be illuminated on the
power supply when the power is off. An illuminated green light indicates that the
power supply is operating.
Redundant power supplies are hot-swappable, and can be changed without pow-
ering down the system. New units can be ordered directly from Supermicro (see
contact information in the Preface).
Changing the Power Supply:
If your chassis includes a redundant power supply (at least two power mod-1.
ules), you can leave the server running and remove only one power supply. If
your server has only one power supply, you must power down the server and
unplug the power cord.
2. Push the release tab (on the back of the power supply) as illustrated.
3. Pull the power supply out using the handle provided.
4. Replace the failed power module with the same model.
5. Push the new power supply module into the power bay until you hear a click.
6. Plug the AC power cord back into the module and power up the server.

Chapter 6
Rack Installation
6-1 Overview
This chapter provides a quick setup checklist to get your chassis up and running.
Following these steps in the order given should enable you to have the system
operational within a minimal amount of time.
6-2 Unpacking the System
You should inspect the box which the chassis was shipped in and note if it was
damaged in any way. If the chassis itself shows damage, you should le a damage
claim with the carrier who delivered it.
Decide on a suitable location for the rack unit that will hold your chassis. It should
be situated in a clean, dust-free area that is well ventilated. Avoid areas where
heat, electrical noise and electromagnetic elds are generated. The system needs
to be placed near a grounded power outlet. Be sure to read the Rack and Server
Precautions in the next section.
6-3 Preparing for Setup
The box your chassis was shipped in should include two sets of rail assemblies and
the mounting screws needed for installing the system into the rack. Also included
is an optional square hole to round hole converter bracket, for use in racks with
round mounting holes. Please read this section in its entirety before you begin the
installation procedure outlined in the sections that follow.
Choosing a Setup Location
Leave enough clearance in front of the rack to enable you to open the front •
door completely (~25 inches).
Leave approximately 30 inches of clearance in the back of the rack to allow for •
sufcient airow and ease in servicing.
This product is for installation only in a Restricted Access Location (dedicated •
equipment rooms, service closets and similar environments).
SC847 Chassis Manual
6-2
6-4 Warnings and Precautions
Rack Precautions
Ensure that the leveling jacks on the bottom of the rack are fully extended to •
the oor with the full weight of the rack resting on them.
In single rack installations, stabilizers should be attached to the rack.•
In multiple rack installations, the racks should be coupled together.•
Always make sure that the rack is stable before extending a component from •
the rack.
You should extend only one component at a time - extending two or more si-•
multaneously may cause the rack to become unstable.
General Server Precautions
Review the electrical and general safety precautions that came with the com-•
ponents you are adding to your chassis.
Determine the placement of each component in the rack • before you install the
rails.
Install the heaviest server components on the bottom of the rack rst, and then •
work upwards.
Use a regulating uninterruptible power supply (UPS) to protect the server from •
power surges, voltage spikes and to keep your system operating in case of a
power failure.
Allow the hot plug hard drives and power supply modules to cool before touch-•
ing them.
Warning!
!
!
6-3
Chapter 5: Rack Installation
Always keep the rack's front door and all panels and components on the servers •
closed when not servicing to maintain proper cooling.
6-5 Rack Mounting Considerations
Ambient Operating Temperature
If installed in a closed or multi-unit rack assembly, the ambient operating tempera-
ture of the rack environment may be greater than the ambient temperature of the
room. Therefore, consideration should be given to installing the equipment in an
environment compatible with the manufacturer’s maximum rated ambient tempera-
ture (TMRA).
Reduced Airow
Equipment should be mounted into a rack so that the amount of airow required
for safe operation is not compromised.
Mechanical Loading
Equipment should be mounted into a rack so that a hazardous condition does not
arise due to uneven mechanical loading.
Circuit Overloading
Consideration should be given to the connection of the equipment to the power
supply circuitry and the effect that any possible overloading of circuits might have
on overcurrent protection and power supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
Reliable Ground
A reliable ground must be maintained at all times. To ensure this, the rack itself
should be grounded. Particular attention should be given to power supply connec-
tions other than the direct connections to the branch circuit (i.e. the use of power
strips, etc.).
SC847 Chassis Manual

6-6 Rack Mounting Instructions
This section provides information on installing the chassis into a rack unit with the
rails provided. There are a variety of rack units on the market, which may mean
that the assembly procedure will differ slightly from the instructions provided. You
should also refer to the installation instructions that came with the rack unit you are
using. NOTE: This rail will t a rack between 26.5" and 36.4" deep.
Identifying the Sections of the Rack Rails
The chassis package includes two rail assemblies in the rack mounting kit. Each
assembly consists of three sections: An inner chassis rail which secures directly to
the chassis, an outer rail that secures to the rack, and a middle rail which extends
from the outer rail. These assemblies are specically designed for the left and right
side of the chassis.

Locking Tabs
Each inner rail has a locking tab. This tab locks the chassis into place when installed
and pushed fully into the rack. These tabs also lock the chassis in place when fully
extended from the rack. This prevents the server from coming completely out of
the rack when when the chassis is pulled out for servicing.

C-7 Front Jumper Locations and Pin Denitions
Explanation of Jumpers
To modify the operation of the backplane,
jumpers can be used to choose between
optional settings. Jumpers create shorts
between two pins to change the function
of the connector. Pin 1 is identied with
a square solder pad on the printed circuit
board. Note: On two pin jumpers, "Closed"
means the jumper is on and "Open" means
the jumper is off the pins.

The MG9072 is an enclosure management
chip that supports the SES-2 controller and
SES-2 protocols.
2. Upgrade Connectors
The upgrade connectors are designated JP69,
JP78, and JP115 and are used for manufactur-
er's diagnostic purposes only.
3. Activity LED Header
The activity LED header, designated JP26,
JP47 and JP108, is used to indicate the activ-
ity status of each SAS drive. The Activity LED
Header is located on the front panel. For the
Activity LED Header to work properly, connect
using a 10-pin LED cable.
4., 5., 6. I 2C Connectors
The I 2C Connectors, designated JP37, JP95,
JP52, JP96, JP116, and JP117, are used

Appendix D: SAS-846A Backplane Specications
D-7 Front Jumper Locations and Pin Denitions
Explanation of Jumpers
To modify the operation of the backplane,
jumpers can be used to choose between
optional settings. Jumpers create shorts
between two pins to change the function
of the connector. Pin 1 is identied with
a square solder pad on the printed circuit
board. Note: On two pin jumpers, "Closed"
means the jumper is on and "Open" means
the jumper is off the pins.

Explanation of Jumpers
To modify the operation of the backplane,
jumpers can be used to choose between
optional settings. Jumpers create shorts
between two pins to change the function
of the connector. Pin 1 is identied with
a square solder pad on the printed circuit
board. Note: On two pin jumpers, "Closed"
means the jumper is on and "Open" means
the jumper is off the pins.

E-12 Supported Cascading Conguration
Cascading allows the system to access data at a faster rate by allowing several
backplanes to share resources to reduce latency time.
The rst backplane in a cascaded system requires a motherboard and HBA. Other
servers require a power control card, not a motherboard and HBA.
Other Considerations:
Cascading supports up to one hundred twenty two hard drives•
Use the same cables for all single port congurations•
